In Germany February 2, 1950 l Public Law 619, August 23, 1954 Patent expires February 2, 1970 7 claims. `(ci. zo-ss) This invention relates to a door or window construction in which the sash is arranged so as to be both sw1ng v able about a vertical axis and tiltable about a horizontal axis.

`One object of the present invention isto provide a door or window construction which is so designed as to seal the sash with weathertightiit so that draft 1s completely eliminated. An essential feature of the present inventlon consists accordingly in a door or window construction wherein thev sash, which is selectively swingable about a vertical l axis as well as tiltable about a horizontal axis, isv in addition provided witha raising device bymeans of which it can be raised or lowered in vertical direction. According to another feature of the present invention the arrangement is'` such that the sash can but be swung about the vertical axis in its raised position. The arrangement.

can also be suchthat both swinging about a vertical axis l and tilting abou-t a horizontal axis is but possible in raised position of the sash.

Another object of the present invention is simplification of the devices provided for raising, swinging and tilting the sash, in that the fittings for raising and the tittings for swinging and tilting are combined into one unit. f Y

A feature of the present invention resides `therefore specifically in that a corner fitting for fixing both the vertical swinging axis and the horizontal tilting axis is at the same time combined into one unit with the raisin device for raising the sash.

A raisable and tiltable swinging sash .constructedin Y he novel features which are considered characterisn tie' for `the invention are set. forth in lparticular in the appended claims. i The invention itself, however, both .f I t9 its onstructionand its method of operation, together with additional objects and advantagesthereof, will be bes't understood from the following description of two vspecic embodiments when read in connection with the accompanying drawings, -in which: Figfl is an elevational View of a sash constructed in accordance .with the present invention and showing the "'s'ash in its lowered position,

Fig. 6 `is a side elevational view of a modification of the present invention. i'

Referring now to the drawings it will be seen that the invention illustrated in Fig. l includes a sash 10 which is operatively mounted on a window frame 11 by means of iittings 12, 13 and 1 4. The lower cross member of the sash is provided with a groove 15 with which it is in sealing engagement with a molding 16 incorporated in the lower cross member of the xed Window frame when the sash is in its lowered position shown in Figs. 1 and 2. The side fitting4 12 comprises a stayrod 17 pivotally connected by a joint 17a at 17b to the frame 11, and a bush-like member 1S turnably attached to the sash and slidingly arranged on the stay rod 17 coupled with the sashby a ratchet device 17o, or, the like. As is specifically shown in Fig. 4` theylower side fitting 13 in- -cludes a base plate '19- of relatively great length which is fastened to the'xed window frame by screws 19a. A bushing or hollow rod 22 adapted for receiving a'hin'ge pin 23 is hinged on the lower end of the base plate between two bearing eyes 20 by a fulcrum pin 21.4 vThe hinge pin 23 carries on its upper end which is extended beyondthe bushing 22 a hinge member 24, 24 vwhich is slidably arranged for up-and-downmotion between the legs of a ULshaped fitting 2S`mortised in the window frame iti. The flap 24'.' of the hinge member 24 has an opening Atherein rwhich-is in engagement )with an .eoeentric /28 turnable about a fulcrum member 27 in the U-shaped fittingl 25. Anose V29 made integrallyy with the base plate 19v engages the hinge member 24 at the top so that raisingthe hinge member 24 out of the hinge pin y23:, that is, separating the sash from the Window frame,is prevented when the sash is closed. rA handle 30 coupled with the fulcrum member 27 by a square pin serves for operating the eccentric 28,V Whereas for opening the sash a knob 31 is provided thereon in place of the conventional handle.

The iitting 14 comprises a hinge-like member 3 2 fastened to the window `frame and a Ahinge-like member 33 secured to the sash. A bolt 34V operatively arrangedfin the member 32 permits coupling together of the members 32 and 33 when the sash is raised a distance h (Fig. 4)

is a member of the iitting 12 and operativelyl mounted and the aforesaid members are .thus brought into alignment with one another. Y l

As is clearly shown in 'Fig.- 1 the vertical swinging axis A-B of the sash is fixed by both the stay rod 17, which onthe window frame, and the hinge pin 2 3 of the lower "sideiitting 13, andthe horizotaltilting'axis jof the sash is fixed by iboth the axis of the fulcrum pin V21 nowf be coupled by the bolt :i4-with the window frame preliminary to tilting about the axis C-D (Fig. 3),." The land the axisof the hinge member 32.

Figs. 1 and Y2 show the sash 10 in its lowered, closed position. In this position it cannot be swung or tilted because the molding 16 preventsl such movement.

When it iss'desired to open thesash, that is to swing it about the vertical axis -A'-B, or to tilt it about the horilzontal axis C-l the handle 30 is turned and with it Athe eccentric-28, 'andthus the sash ltllcarryingithefulsash is guided in known manneralong the stay'rod 17 ytill it abuts with its bushing 18 against the stop provided lat theend of .the stay roda;

When it isV desired to'openthe sash, that is, toswing mately 90 degrees.

y the knob 31.

itabout the axis A-B, then the bolt 34 is not coupled with the hinge member 33, whereas the stay rod 17 is arrested on the window frame.

Y j jIf occasion arises,` the sash in its lowered position may 4also at another point besecured to the window frame against opening, Vfor example, by means of hooks, or

lgtliide pins acting in the manner of a bayonet joint, or the e. Y Unhinging of the sash is possible by swinging it about its 4vertical axis A-B into an open position ofrapproxi- In this position the sash together iwith its fitting 24 can be lifted ofi its hinges by passing the stop 29, as in this position the flap-like portion 24 of th'exfitting24 will be in the position 24".

`No closing gear need be provided in connection with A Also without closing gear the sash is securely locked in the window frame when closed. Thus f is attained a sash of relatively simple practical construction whichcanbe produced just as economically as con- ,ventional swinging sash. As compared with the latter the Vvsashprovided by the present invention has the advantage of greater weathertightness and better closing j 'andi-permits, in addition, to use ,it b oth as swinging and ltilting sash. v

Linder certain circumstances it is also possible to locate the horizontal tilting axis C-D in the apex or centerline of the molding 16 and groove 15 respectively so that the l groove moves about the molding when the sash is tilted.

For this purpose it is necessary to sink the lower corner fitting correspondingly so that also in this case it will be in alignment with the tilting axis.

Such a modification is shown in Fig. 6. The fulcrum `pin 121 of the lower corner fitting accordingly is so the molding 116, the bushing 122 Vbeing inwardly bent .at its lower end.

The sash is consequently also in its lowered position gcapable of tilting, whilst for swinging it about the axis A-B it must, in the first place, be raised so much that its lower edge can be swung over the top of the molding The arrangement of the raising device on a hinge joint p cooperating with both thev vertical swinging axis and the horizontal tilting axis renders it possible that relatively few fittings are needed for operating the sash according to. the present invention. As the bearing or base plateV l for the tiltable hingejoint may be subjected to a relatively large load, 'it is to the purpose to strengthen it accordingly.

It is thought vfrom the foregoing description that the advantages and novel features of theinvention will be readily apparent. Y

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fal within the scope of the appended claims. A
